PEG

Folate-PEG-CH2CO2-NHS, MW 1,000 is an amine reactive PEG derivative. The coupling between amine and NHS ester forms an amide bond. The folate allows selective binding with folate receptor found in many tumor cells. Reagent grade, for research purpose.

Folate-PEG-CH2CO2-NHS, MW 2,000 bind selectively with folate receptor which is constantly overexpressed in a number of cancerous cells. The folate binds strongly with folate receptors found in tumors of the ovary, lung, endometrium, kidney, breast, bladder, and brain. Reagent grade, for research purpose.

Folate-PEG-CH2CO2-NHS, MW 3,400 is an amine reactive PEG polymer. The folate has strong binding affinity with folate receptor found in many malignant cells. Reagent grade, for research purpose.

Folate-PEG-CH2CO2-NHS, MW 10,000 is an active ester polydisperse PEG which is reactive with amine to form a covalent amide bond. The folate binds strongly with folate receptors found in tumors of the ovary, lung, endometrium, kidney, breast, bladder, and brain. The functional polymer can be used for development of targeted nanotherapeutics based on cancer biomarker. Reagent grade, for research purpose.

Folate-PEG-OH, MW 1,000 is a linear heterobifunctional polyPEG with a hydroxyl group for further derivatization. The folate can bind selectively and strongly with folate receptors expressed in various cancer cells. Reagent grade, for research purpose.

Folate-PEG-OH, MW 10,000 is a heterobifunctional PEG derivative which can bind strongly with cancer biomarker, i.e. folate receptor. The polymer can be used to prepare liposome for delivering therapeutic agents. Reagent grade, for research purpose.

Lipoamide-PEG-Mal, MW 1,000 is a lipoic acid PEG derivative for surface modification of metallic particles/film. The maleimide moiety can react with cysteine or thiol molecule to form a thioether linkage. PEG chain linked to lipoic acid offers good water solubility, flexible linker structure, and enhanced biocompatibility. Reagent grade, for research purpose.

Lipoamide-PEG-Mal, MW 2,000 is a surface-active PEG derivative. Lipoic acid is a good metal chelator for many biomedical applications, such lipoic acid modified gold nanoparticles (AuNP) for therapeutics. The maleimide moiety can react with cysteine or thiol molecule to form a thioether linkage. Reagent grade, for research purpose.

Lipoamide-PEG-Mal, MW 3,400 is a maleimide polyPEG to form a thoether bond when reacted with thiol or cysteine. The polymer is also surface active which can bind to metal surface through disulfide (SS-) bond. Reagent grade, for research purpose.
